Title: Innovations of Katsuo Wada
Introduction
Katsuo Wada is a prominent inventor based in Hitachi, Japan. He has made significant contributions to the field of gas turbine technology, holding a total of 14 patents. His work focuses on enhancing the efficiency and durability of gas turbine components.
Latest Patents
One of Wada's latest patents is a method for producing a ceramic-coated blade for gas turbines. This innovative method prevents the thickening of an Al2O3 layer at the interface between the ceramic layer and the primary layer, effectively suppressing the separation of the ceramic layer over time. The primary layer is formed using a powder of MCrAlY alloy, specifically Co—32%Ni—21%Cr—8%Al—0.5%Y, applied to a substrate made of a heat-resistant nickel base alloy known as Rene'-80. Additionally, a heat-resistant ceramic layer is created using a mixture of ion-conductive ZrO2—8wt.%Y2O3 ceramic and insulative ceramic, such as Al2O3. This mixture can either have a columnar structure or a porous structure, enhancing the performance of the gas turbine.
Another notable patent involves a gas turbine design that includes a compressor and a combustor. This combustor features two fuel supply systems: one for a high-calorific fuel and another for a lower-calorific fuel. The turbine is driven by combustion gas from the combustor, which is controlled to maintain stable pressure during fuel switching.
